***

STEPS TO REPRODUCE

2. Create a title with a text box. Add image or movie clip, some fades.
3. Put it in Timeline, hit render

OBSERVED RESULT
See a 5 seconds of <<INVALID>>, no title ; images / clips shows up but no fades.

EXPECTED RESULT
Have a title and faded transitions

STEP TO REMEDY 
Install native distro version (on Arch and Asahi Fedora Remix)

Comment 1 Eric Mesa 2024-02-16 21:11:22 UTC

I'm having the exact same issue. 

Fedora 38
System reports:
KDE Plasma 5.27.9
QT 5.15.11

Flatpak info from Kdenlive:
23.08.4

When I last saw a bug report for this, it was in mlt repo in 2018. Does flatpak use system mlt? Or bring its own?

Rendered my file in the appimage for the same version of kdenlive and the issue does not appear.

Comment 2 Jean-Philippe Monteiro 2024-02-18 10:08:14 UTC

Same on Debian testing

From 'flatpak list' :
KDE                                           org.kde.kdenlive                23.08.4  (stable)
KDE Application Platform     org.kde.Platform               5.15-23.08 

provider: flathub

Comment 3 Jean-Baptiste Mardelle 2024-02-21 08:16:23 UTC

This is a packaging issue related to Flatpak, see:
